Input current into the load must be monitored with an appropriate ammeter. Transmitter input current and voltage can be monitored also, but the meter must use averaging function for reducing error due to communications packets. 6.1.4 Loads A single load is required for 5 V with a maximum current of 1 A. The load can be resistive or electronic. 6.1.5 Oscilloscope A dual-channel oscilloscope with appropriate probes is used to observe the COMM_DRV signal at bq51013EVM-725 TP3 and other signals. . 6.1.6 Recommended Wire Gauge For proper operation, 22 AWG wire is recommended when connecting the bq500210EVM-689 to input supply and bq51013EVM-725 to load. 6.2 Equipment Setup • • • With power supply OFF, connect supply to bqTESLA™ transmitter. Connect Vin positive power source to J1 and negative terminal of the Vin source connected to J2. Do not place bqTESLA™ receiver on transmitter. Connect load to J3 with return to J4, monitor current through load with ammeter, and monitor current to load at TP7. All voltmeters must be Kelvin connected (at the pin) to the point of interest. • 6.2.1 Equipment Setup Diagram The diagram in Figure 4 shows the test setup.

Some key notes follow: 6.2.2.1 START UP NO RX Turn on VIN, and observe that the Green Power LED D2 illuminates. Status LED D5 will be off until power tranfer starts. Apply the scope probe to the test point TP1 and observe a single pulse bursts approximately every 0.5 s. This is Analog Ping probing environment for the presence of a receiver placed on the Tx coil. 6.2.2.2 APPLY RX Place bq51013EVM-725 EVM on the top of the transmitting coil. Align centers of the receiving and transmitting coils across each other. In the next few seconds, observe Status LED D5 illuminates green, indicating that communication between transmitter and receiver is established and power transfer has began. • Buzzer will sound at the start of power transfer. Status LED D5 flashes green light during power transfer. • Typical output voltage is 5 V, and the output current range is 0 mA to 1A. • Observe continuous sine-wave on the test point TP1 when power transfer is active, frequency will be between 110kHz and 205kHz. • Make tests and measurements applicable to a normal 5V power supply. 6.2.2.3 EFFICIENCY To measure system efficiency, measure the output voltage, the output current, input voltage, and input current and calculate efficiency as the ratio of the output power to the input power. It is recommended to average the input current, the comm pulses will modulate the input current distorting the reading. See Figure 5 for efficiency. 6.2.2.4 PARASITIC METAL OBJECT DETECTION To test the Metal Object Detection (MOD) function. In addition to loading on the output of bq51013EVM725, apply an electronic load in constant power mode between secondary GND (J4) and TP12 – the output of the secondary side rectifier. Increasing load power from 0 W to over 0.5 W, observe LED D5 of bq500210EVM turning red and the power transfer stopped in approximately 20 s after the MOD threshold was exceeded. 6.2.2.5 THERMAL PROTECTION, NTC Thermal protection is provided by an NTC resistor connected to JP1. At 1.00V on the sense side (U1-2) thermal fault will be set and unit is shutdown, Status LED D5 will illuminate red. Typical resistor value for fault is 850 ohms. System will try to restart in 5 minutes.

Efficiency v Power, HPA689 Transmitter and HPA725 Reciver 7 bq500210EVM-689 Assembly Drawings and Layout The following figures show the design of the bq500210EVM printed-circuit board (PCB). The EVM has been designed using a 4-layer, 2-oz, copper-clad circuit board 13.2 cm × 7.24 cm with all components in a 4.5-cm x 4.5-cm active area on the top side and all active traces to the top and bottom layers to allow the user to easily view, probe, and evaluate the bq500210 control IC in a practical application. Moving components to both sides of the PCB or using additional internal layers can offer additional size reduction for space-constrained systems. Coil Grounding – A ground plane area under the coil is recommended to reduce noise coupling into the receiver. Ground plane for the EVM is slightly larger than coil footprint and grounded at one point back to the circuit area. Coil Stack Up and Mounting – The EVM mounting stack-up is as follows: 1. Transmitter coil thickness – 6 mm 2. Sil pad – 0.5 mm 3. Al shim – 1.5 mm The overall stack-up is under compression from the cover plate. The AL shim and sil pad is optional for a customer solution optimized for size. Note: The cover thickness is 0.93 inch, or 2.4 mm is the z-gap thickness for the transmitter. 12 bqTESLA Wireless Power Transmitter Manager EVM SLVU467A – June 2011 – Revised October 2012 Submit Documentation Feedback Copyright © 2011–2012, Texas Instruments Incorporated bq500210EVM-689 Assembly Drawings and Layout www.ti.com Figure 6.
